dh_makeshlibs contains the following code to look for shared objects that
should be represented in shlibs:
if ($objdump=~m/\s+SONAME\s+(.+)\.so\.(.+)/) {
elsif ($objdump=~m/\s+SONAME\s+(.+)-(.+)\.so/) {
I've seen several different forms of the second regex. dh_makeshlibs
uses one, Lintian had a different one, and dpkg-shlibdeps had yet another
one.
In investigating handling of unversioned SONAMEs in Lintian, I confirmed
with Raphael Hertzog the regexes used by dpkg-shlibdeps, which are in the
split_soname function in that program. I just changed Lintian to match,
and I recommend changing dh_makeshlibs as well. I'm going to propose
canonicalizing the parsing in Debian Policy.
The only significant difference is that dpkg-shlibdeps requires that the
version component in the second regex start with a number and end with .so.
The split_soname function is:
sub split_soname {
my $soname = shift;
if ($soname =~ /^(.*)\.so\.(.*)$/) {
return wantarray ? ($1, $2) : 1;
} elsif ($soname =~ /^(.*)-(\d.*)\.so$/) {
return wantarray ? ($1, $2) : 1;
} else {
return wantarray ? () : 0;
}
}
so changing to m/\s+SONAME\s+(.+)-(\d.*)\.so\s*$/ would make the regexes
match the same strings for all practical purposes.
For Lintian, I also changed the .+ regexes to .* to match exactly, but
I can't imagine a legitimate case in which it would make a difference.
